§ Mr. Campbell-Savoursasked the Secretary of State for Foreign and Commonwealth Affairs, pursuant to the Answer of 26 January if he will now specify the precise dates on which (a) investigations were first initiated to identify the source or sources of information given to Mr. Duncan Campbell about Project Zircon and (b) these investigations were intensified.
§ Mr. RentonInitial inquiries were begun by GCHQ in the summer when the Government first became aware of the BBC's plans for one or more programmes. More detailed investigations were initiated by GCHQ in the week beginning 6 October, when the intention to include specific material on a secret defence project in the BBC series "The Secret Society" became known. These investigations were intensified as further details became available about what information Mr. Campbell might have obtained, and in particular in the week beginning 19 January. Since the police investigation began, GCHQ has handed over responsibility to them and is providing them with full assistance.
